Resolva a integral abaixo por substituição trigonométrica e teste o
seu resultado. Dica: você vai ter que começar com a mudança de
variável $u=2x$.

se precisar. Vou dar algumas dicas no quadro.

{\bf Dicas:}
\ssk
1) Nestas questões o que vai contar mais pontos é você organizar as
contas de modo que cada passo seja fácil de entender, de verificar, e
de justificar -- ``chegar no resultado certo'' vai valer relativamente
pouco.
\ssk
2) Recomendo que vocês usem o método das ``caixinhas de anotações''
nas mudanças de variável... numa caixinha de anotações a primeira
linha diz a relação entre a variável nova e a antiga, todas as outras
linhas são consequências da primeira, e dentro da caixinha de
anotações você pode usar as gambiarras com variáveis dependentes e
diferenciais, como isto aqui: $dx = 42\,du$...
\ssk
3) ...por exemplo:
%
$$\bmat{
s = \sen θ \\
\sqrt{1-s^2} = \cos θ \\
\frac{ds}{dθ} = \cos θ \\
ds = \cos θ \, dθ \\
θ = \arcsen s \\
}
$$

{\bf Questão 3}
\T(Total: 1.0 pts)
\msk
No curso nós definimos que {\sl pra nós} a ``fórmula'' do TFC2 seria
esta aqui:
%
$$\ga{[TFC2]}
\;=\;
\left( \Intx{a}{b}{F'(x)} \;=\; \difx{a}{b}{F(x)} \right)
$$
Mostre que quando $a=1$, $b=3$ e
%
$$F(x) =
\begin{cases}
2x & \text{quando $x<2$}, \\
x & \text{quando $x≥2$} \\
\end{cases}
$$
a fórmula $\ga{[TFC2]}$ é falsa.
\msk
Dicas: o melhor modo de fazer isto é representando graficamente $F(x)$
e $F'(x)$ e calculando certas coisas a partir dos gráficos. Considere
que o leitor sabe calcular áreas de retângulos, triângulos e trapézios
no olhômetro quando as coordenadas deles são números simples, mas
complemente os seus gráficos com um pouquinho de português quando nem
tudo for óbvio só a partir dos gráficos.

{\bf Questão 4
}
\T(Total: 1.0 pts)
\msk
Seja $f(t)$ a função no topo da página seguinte.
Seja
%
$$F(x) \;=\; \Intt{3}{x}{f(t)}.$$
Desenhe o gráfico de $F(x)$ em algum dos grids vazios da próxima
página. Indique claramente qual é a versão final e quais desenhos são
rascunhos.
